The transformations with non-vanishing \(\epsilon \)  at infinity are improper gauge symmetries since the surface term (REF ) does not vanish in this case [1]}. Because the asymptotic value of the supersymmetry parameter is an arbitrary (even) function \(\epsilon ^{(0)}(\theta , \varphi )\)  on the 2-sphere, we have given a formulation of supergravity with an infinite number of improper fermionic gauge symmetries.
